Questions
How big is the Vfd driver PCB?
It measures 41.8 × 139.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vfd driver use?
26 parts, built around the 74HC595 and ULN2803A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Vfd driver KiCad files?
From the Jkillelea/VFD-PCB repository on GitHub, at the commit this page was made from: the board is vfd_driver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vfd driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jkillelea before reusing the design.
